Review Comment:
Fair points, I can just change newDVRefs to a multimap. Are we sure we would
want to just leave deleteFilesBySpec as is? I guess it's not much of a memory
concern since as @RussellSpitzer said it's just refferences but are we worried
about the state of that map having potential duplicates?
